The butterfly is common in montane and secondary forests at low to moderate elevations (Alt.30m - 1000m).
Both ssp.dhyana and ssp.fabia occur together from central to north Thailand. It seems to be a transition zone of both subspecies. In some localities of Chiang Mai and Lampang, N.Thailand, ssp.fabia, ssp.dhyana and Pseudocoladenia fatua are found sympatrically.
